David William Valencia Antonio
David William Valencia Antonio was born December 29, 1963, in Nagtupacan, Santo Domingo, Ilocos Sur. He studied philosophy at San Pablo Seminary, Baguio, and theology at the Immaculate Conception School of Theology in Vigan, and earned a doctorate in theology from The Catholic University of America.
He was ordained a priest for Nueva Segovia on December 1, 1988. He taught at the Immaculate Conception School of Theology, becoming dean of studies in 1993 and later rector, served as parish priest of Santa Lucia, Ilocos Sur, from 2005, and later as vicar general of Nueva Segovia. His episcopal motto is Ut vitam habeant ('That they may have life').
He was consecrated a bishop on August 2011, served as Auxiliary Bishop of Nueva Segovia, as Apostolic Administrator of San José in Mindoro, and as Bishop of Ilagan (2019–2025), and was appointed Metropolitan Archbishop of Nueva Segovia on November 4, 2025, taking possession on January 14, 2026.
No decree, circular, permission, suppression, expansion, or transfer of the Traditional Latin Mass by Archbishop Antonio, in Ilagan or in Nueva Segovia, was found. His chairmanship of the CBCP Episcopal Commission on Liturgy is a conference role; no liturgy-commission decree or guideline authored by him was found, and the chairmanship is not counted as a diocesan act.
The Nueva Segovia tenure began January 14, 2026, so the finding there covers roughly nine months to the as-of date; no_record for Nueva Segovia means 'none found in a short tenure,' not a settled long-run record. The Ilagan and Nueva Segovia diocesan Facebook pages and chancery circular PDFs could not be retrieved by text fetch, so a Facebook-only circular would not have surfaced.
